No, using Haskell directly is not an option (at least with current 
compiler technology). Their performance requirements are very high, and 
the signal processors have quite limited memory, so putting a Haskell 
RTS on them wouldn't work.

Yes, Erlang is used in some applications, but that's more for "control 
programs", not for numerical computations.

I hope you will succeed in making real-time signal processing in Haskell
